英文摘要： Massive MIMO wireless transmission technique can deeply exploit spatial dimension wireless resources, further improving the frequency and power efficiencies by an order of magnitude. It has become one of the most potential techniques for the future new generation mobile communications and has received extensive attention from researchers. Focusing on the bottleneck problem for channel information acquisition, as well as the system implementation complexity problem, involved in the massive MIMO wireless transmission, we propose and investigate wideband massive MIMO wireless transmission with dynamic pilot reuse in this project. The main research contents include the new characteristics and three dimensional statistical model of the wideband massive MIMO channels in the space, time and frequency domains, channel information acquisition with dynamic pilot reuse, robust precoded downlink multiuser transmission and its low complexity implementation, and robust uplink multiuser detection and its low complexity implementation. Our aims are to develop the three dimensional statistical model of the wideband massive MIMO channels in the space, time and frequency domains, theoretical approaches for channel information acquisition with dynamic pilot reuse, and theoretical approaches for the corresponding optimal transmission as well as the low complexity implementation. It is expected to achieve systematical results in the wideband massive MIMO wireless transmission technique, providing effective solutions to the bottleneck problem for channel information acquisition and the system implementation complexity problem.
